[0044] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0045] It should also be understood that the terminology used in this specification of embodiments of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the present invention. As used in this specification of embodiments of the present invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0046] See Figures 1-11 This utility model provides a reflux elevator. The reflux elevator includes a cabinet 1 with at least four flow channels 11, including a lower left flow channel, a lower right flow channel, an upper left flow channel, and an upper right flow channel, wherein any two flow channels 11 are respectively configured as an inlet and an outlet; a lifting mechanism 2 installed inside the cabinet 1; a horizontal conveying mechanism 3 installed on the lifting mechanism 2 and driven by the lifting mechanism 2 to move vertically along the cabinet 1; and a control device electrically connected to the lifting mechanism 2 and the horizontal conveying mechanism 3. When the horizontal conveying mechanism 3 is at its upper limit position of the lifting stroke, it is on the same horizontal plane as the upper left and upper right flow channels; when the horizontal conveying mechanism 3 is at its lower limit position of the lifting stroke, it is on the same horizontal plane as the lower left and lower right flow channels. The specific descriptions of each component are as follows:

[0047] In this embodiment, the cabinet 1 is provided with at least four flow channels 11 (one at the top and one at the bottom, one on the left and one on the right) that can be flexibly configured with inlets / outlets to adapt to different flow direction requirements (such as left in, right out or right in, left out). The flow direction can be switched by a control device to achieve multi-directional material return. A flow channel sealing plate can also be provided to close unused flow channels 11. The lifting mechanism 2 is used to drive the horizontal conveying mechanism 3 to move up and down to match the flow channels 11 at different heights. The horizontal conveying mechanism 3 is used to receive or transfer materials after being lifted into position, ensuring horizontal alignment with the flow channels 11. The control device is used to coordinate the lifting and horizontal conveying actions to achieve an automated process.

[0048] This reflux elevator has multiple flow channels 11 that can be flexibly configured with inlets / outlets to adapt to different flow direction requirements. Combined with the control device, it achieves a highly automated process.

[0049] See also Figures 1-11 In this embodiment, the horizontal conveying mechanism 3 includes a base plate 31, a first conveying module 32 and a second conveying module 33. The first conveying module 32 and the second conveying module 33 are mounted parallel to each other on the base plate 31, and the base plate 31 is connected to the lifting mechanism 2.

[0050] Specifically, the base plate 31 serves as the mounting foundation for the first conveying module 32 and the second conveying module 33, and must possess rigidity to bear the load. The first conveying module 32 and the second conveying module 33 are driven independently and both support bidirectional material transport (e.g., the first conveying module 32 and the second conveying module 33 simultaneously transport from left to right, or simultaneously transport from right to left). The parallel arrangement of the first conveying module 32 and the second conveying module 33 provides stability to the support carrier, and the bidirectional material transport capability adapts to different flow direction requirements depending on the scenario.

[0051] The first conveying module 32 and the second conveying module 33 are driven independently. The modular design of the components facilitates maintenance and allows for quick replacement of damaged modules.

[0052] Furthermore, the reflux elevator also includes: a lateral adjustment mechanism 5, including a lead screw 51, a guide rail 52 and a sliding member 53, wherein the lead screw 51 is mounted on the base plate 31 and the sliding member 53 is slidably connected to the guide rail 52; the second conveying module 33 is fixed on the sliding member 53 and is driven by the lead screw 51 to adjust its distance from the first conveying module 32.

[0053] Specifically, the rotation of the lead screw 51 drives the movement of the sliding member 53, adjusting the distance between the second conveying module 33 and the first conveying module 32, thereby adapting to materials of different sizes (such as adjusting the belt spacing to accommodate boxes / pallets). The sliding member 53 cooperates with the guide rail 52 to ensure the stability of the movement of the second conveying module 33.

[0054] Furthermore, the first conveying module 32 includes: a first fixed bracket 321 fixed on the base plate 31; a first drive motor 322 and a first transmission assembly 323 mounted on the first fixed bracket 321; the first transmission assembly 323 includes a first belt and a first pulley group, and the first drive motor 322 is controlled by the control device.

[0055] Specifically, the first fixed bracket 321 provides rigid support for the motor and transmission components, reducing vibration. The first transmission component 323 adopts a combination of a first belt and a pulley system to achieve low-noise, high-speed material transmission. The conveying speed of the first conveying module 32 can be controlled by adjusting the speed of the first drive motor 322 through the control device.

[0056] Furthermore, the second conveying module 33 includes: a second fixed bracket 331, fixed on the sliding member 53; a second drive motor 332 and a second transmission assembly 333, mounted on the second fixed bracket 331; the second transmission assembly 333 includes a second belt 3331 and a second pulley group 3332, and the second drive motor 332 is controlled by the control device.

[0057] Specifically, the second fixed bracket 331 is fixed to the sliding member 53, and the second fixed bracket 331 is fixedly connected to the movable part on the lead screw 51. As the lead screw 51 rotates, the movable part moves, causing the second fixed bracket 331 to move closer to or further away from the first fixed bracket 321. The second drive motor 332 independently controls the direction of the second belt 3331, and works in conjunction with the first conveying module 32 to achieve sorting or return.

[0058] In this embodiment, by adjusting the rotation speed of the first drive motor 322 and the second drive motor 332 through the control device, the conveying speed of the two can be controlled to be the same, so as to realize the smooth conveying of the carrier on the first belt and the second belt 3331. The specific control principle can be determined with reference to existing materials, and this utility model does not make specific limitations on it.

[0059] Furthermore, the return elevator also includes a stop device 6, located at the end of the first conveying module 32 and / or the second conveying module 33.

[0060] Specifically, the number of stopping devices 6 is not specifically limited. Each stopping device 6 includes a blocking cylinder, installed at the end of the conveying module, such as the discharge port. When the blocking cylinder extends, it blocks the material to prevent it from falling or accumulating; when it retracts, it releases the material to downstream equipment. The stopping device 6 is linked with a sensor to achieve precise start and stop. In this embodiment, blocking cylinders are provided at both ends of the first conveying module 32, and at both ends of the second conveying module 33.

[0061] Furthermore, the reflux elevator also includes a detection sensor 7, which is located at the end of the first conveying module 32 and / or the second conveying module 33.

[0062] Specifically, the number of detection sensors 7 is not specifically limited. The detection sensors 7 include photoelectric sensors and proximity sensors, used to detect whether the material is in place or jammed; and to feed back signals to the control device to trigger a stop or alarm. Adding detection sensors 7 can effectively prevent idling or collisions; for example, stopping the first drive motor 322 and the second drive motor 332 when no material is detected. In this embodiment, photoelectric sensors are provided at both ends of the first conveying module 32, and photoelectric sensors are provided at both ends of the second conveying module 33.

[0063] Furthermore, the base plate 31 includes a base plate 311, a reinforcing structure, and a fixing plate 313; the fixing plate 313 is disposed on the lifting mechanism 2, the first conveying module 32 and the second conveying module 33 are respectively disposed on the base plate 311, the base plate 311 is connected to the fixing plate 313 through the reinforcing structure, and the reinforcing structure includes a reinforcing plate 3121 and a reinforcing rod 3122.

[0064] Specifically, the base plate 311 is the main load-bearing surface, directly fixing the conveyor module. Reinforcing plates 3121 and reinforcing rods 3122 are arranged crosswise to resist torsional deformation and ensure horizontality during lifting. The fixing plate 313 is used to connect the lifting mechanism 2. In this embodiment, the fixing plate 313 is also locked to the synchronous conveyor belt.

[0065] The substrate 31 ensures long-term operational reliability through reinforced structure and precision guidance.

[0066] Furthermore, the lifting mechanism 2 includes a synchronous transmission belt 21, a third drive motor 22, a guide assembly 23, and a third pulley block 24; the third drive motor 22 and the guide assembly 23 are respectively fixed on the cabinet 1, and the synchronous transmission belt 21 is connected to the third drive motor 22 and the third pulley block 24 respectively; the horizontal conveying mechanism 3 is connected to the synchronous transmission belt 21 and the guide assembly 23 respectively.

[0067] Specifically, the synchronous transmission belt 21 includes a polyurethane-reinforced steel wire conveyor belt, which has high tensile strength, prevents breakage, and is quieter than a chain. The third drive motor 22 includes a 1.5kW servo motor and a geared motor, and the lifting speed and position accuracy are adjusted by a control device. The guide assembly 23 includes a track to constrain the left and right swing amplitude of the horizontal conveyor mechanism 3, prevent swaying during the up and down movement of the horizontal conveyor mechanism 3, and improve the movement stability. The third pulley block 24 includes at least two pulleys, which are respectively installed at the top and bottom of the cabinet 1. The synchronous transmission belt is sleeved on the two pulleys. In this embodiment, the drive shaft of the third drive motor 22 passes through the pulley at the bottom of the cabinet 1. The operation of the third drive motor 22 drives the drive shaft and the pulley at the bottom of the cabinet 1 to rotate clockwise / counterclockwise, thereby causing the synchronous transmission belt to drive the horizontal conveyor mechanism 3 to rise / fall.

[0068] Furthermore, it also includes: an alarm device 8, installed on the cabinet 1 and connected to the control device; and an adjustable support assembly, installed at the bottom of the cabinet 1, including telescopic legs 91 and / or casters 92.

[0069] Specifically, the alarm device 8 is used to monitor abnormalities such as sensor malfunctions and motor overloads, and provides alarms via sound and light or remote notification. Telescopic legs 91 are used to level the cabinet 1 to adapt to uneven ground; casters 92 facilitate equipment movement and positioning.

[0070] Multiple protections are achieved through sensors, stop devices 6, and alarm devices 8.

[0071] In one embodiment, the cabinet 1 is also equipped with a switch and a display device.
